comment True or false: if a set of 2D points has valid symmetry axes, then at least one of them is equal to a principal component vector
@tziki: Yes, but beware of finite precision and the situation described in Noam D. Elkies's comment.

comment higher-level independence of three or more correlated RVs
I made a guess that moments were a more familiar notion for you, and used them to argue that the equations you will get are always polynomial, but yes, you are right that you may do all this without mentioning moments at all.

comment Why are smooth numbers called “smooth”?
There is a vague analogy with Fourier series. The more weight is carried by high frequencies in a Fourier series, the less smooth the function is. From this point of view, the most smooth functions are composed of finitely many harmonics.
